``` <?php /** * @param true $a * @return true */ function foo(bool $a): bool { return true; } ``` gets changed to: ``` <?php function foo(bool $a): bool { return true; } ``` which is wrong, since type information is lost It should change it to: (the param is not changed, since updating of param type hints isn't implemented yet at all) ``` /** * @param true $a */ function foo(bool $a): true { return true; } ```
